Abstract
We have developed a rapid gas chromatography–mass spectrometry (GC–MS) method for the detailed compositional analysis of 70 underivatized wood extractive components present in quaking aspen ( Populus tremuloides Michx.). Forty-four compounds were unequivocally identified by retention time and mass spectral comparison with standards. An additional 26 chromatographic peaks were assigned to broad chemical classes using retention time and mass spectra features. The results were compared to the respective tert.-butyldimethylsilyl derivatized wood extractives profile, and it was determined that derivatization was unnecessary for the GC–MS analysis of the target compounds.
